Problems with network adapter

I am on a college network and, up until now, I've been able to get out just fine on just client and TCP/IP installed. I needed something on the network, so I had to install Novell to connect up to it. After I installed the Novell services, I was able to get on the network just fine, but I was not able to get out of the network whatsoever. I'm running win2k and have an intel pro/100 s desktop adapter.

I've attempted uninstalling services and protocols both all at once and one at time, as well as uninstalling and reinstalling the network card with combinations of uninstalling and reinstalling services and protocols and such... all to no avail. If anyone can give me any help with this, I would be much obliged.
